You get a sense of it now. Azure Linux 3.0 is the base for the WSL system distro, there all the WSLg (GUI) and now the wslc plumbing happens. It's ephemeral, but you can drop in and look around with wsl --system --user root. An official WSL image of Azure Linux 4.0 is coming in a few weeks that you'll be able to install with wsl.exe --install Azure...(I'm not sure the exact name).
